A method, system and computer program product for coupling forecasting and planning in a production planning tool is provided. In an embodiment of the invention, a method for coupling forecasting and planning in a production planning tool is provided. The method includes invoking a forecasting module in a production planning tool executing in memory of a computer upon demand data to compute a forecasting model. The method also includes retrieving a stochastic vector from the computed forecasting model for a product, the stochastic vector expressing vector of expected values of demand for the product, and linearizing the stochastic vector in a matrix describing a linear model for demand of the product. The method further includes providing the linearized stochastic vector to a stochastic linear program (LP) relaxation of a planning module of the production planning tool.
